MAURICE KANE, OF AUSTIN, ILLINOIS, AND ALBERT GRIEVES, OF SPRING- FIELD, OHIO, ASSIGNORS TO INTERNATIONAL HARVESTER COMPANY, A CORPORATION OF NEW JERSEY.

HAY-STACKER.

Specification of Letters Patent.

Patented Oct. 3, 1905.

Application flied May 17, 1905. Seriai No. 260.750.

Bcit known that we, MAURioE KANE, residing at Austin, in the county of Cook and State of Illinois, and ALBERT Gmuvns, residing at Springlield, in the county of Clark and State of Ohio, citizens of the United States, have invented certain new and useful Improvements in Hay-Stackers, of which the following` is a spccilication, reference being had to the acro companyingdrawings, formingapart thereof.

This invention relates to hay-stackers, and particularly to those having hoisting-derricks forming a part thereof.

The invention consists of a base-frame upon which is rotatably mounted a mast suitably supported laterally by braces secured at their lower ends to the base-frame and at their upper ends to a cap-piece forming a bearing for the rotatable mast. A boom is pivotally attached to the mast above the braces and at its ou ter end has a fork pivotally connected therewith. It projects beyond its pivotal connection with the mast, and a jib is pivotally connected thereto and by a link connection with the mast. A hoisting mechanism is connected with the movable parts of the derrick; and the objects of the invention are to provide a mechanism that will elevate the fork to a higher plane and to provide for a better transmission of power to raise the boom, to improve the construction of the boom whereby its strength and rigidity are increased, to provide improved means for controlling the angle of the teeth of the fork, and to provide improved means for tripping the fork to discharge the load, and to provide means for locking the mast in position when the fork is receiving and elevating the load.

The objects are attained by the mechanism illustrated bythe accompanying drawings, in which- Figure I is a side elevation in perspective of a hay-stacker embodying' the invention. Fig. 2 is a side elevation of a stacker, showing the operation of the elevating-fork. Fig. 3 is a detail of the rear end of the boom and its pivotal connection with the mast. Fig. 4 is a detail of the fork-tripping mechanism, and Fig. is a section of Fig. A on line A B. Fig. 6 is an enlarged view of the fork, showing the manner in which it is pivotally connected with the boem; and Fig. 7 is a cross-section on line C D of Fig. 6.

The same reference-numerals represent like parts throughout the several views. u'

I is an A-shaped Vbase-frame having crosssills 2 and 3 at opposite ends thereof and an intermediate cross-sill 4 near its center, upon which is pivotally mounted a mast 5, that is supported laterally by means of braces (i, 7, 8, and 9, secured at their lower'ends to the base-frame and at their upper ends to a cappiece 10, in which the mast 5 is rotatably mounted. Secured to the mast above the cappiece is a band 1I, and a strut 1I' forms a part thereof, and 12 is a truss-rod which has its opposite ends secured near the top and bottom of the mast and its middle portion engaging with the strut. The band I1 rests upon the cap-piece, and the weight of the mast and parts carried thereby is supported thereon. Pivotally connected with the mast above the cap-piece 10 is a boom 13, comprising two arms that have their ends connected together at one side of the pivotal connection bymeans of the casting 14 and diverge outward at their opposite ends, which are pivotally connected with a fork l5 by means of the arms 13', pivotally connected with brackets 14', secured to the cross-bars 15', as shown in Figs. 6 and 7. A cross-bar I6 connects the diverging ends of the boom-bars, and 17 and I8 are additional cross-bars connecting them at intermediate points toward the mast. A jib 19, comprising two bars, one upon each side of the mast, having their lower ends pivotally connected with the casting I4 and having sheaves 2O and 21 at its upper end, is iieXiblyconnected with The elevating-fork is one made after a common form, having a rigid vertical standard 23 forming a part thereof, to the upper end of which is attached a cable 24, that passes under a sheave 25, mounted on the cross-bar I7, and upward and over a second sheave 26, mounted upon the mast a suiiicient distance above the pivotal connection of the boom therewith to form a parallel-motion device to retain the teeth of the fork in an approximately hori- Zontal position while tbe fork is being elevated to deposit its load and then downward along the mast to ahand-lever 27, to which it is adjustably secured by means of the link 28, having a series of holes at its lower end to provide for such adjustable connection. Two bars 29 and 30 are secured to the mast upon the upper end of the mast by means of a link 22.

IOO

opposite sides thereotI by means of a bolt 31 l mounted on the boom, and ajib pivotallv coin and brace The hand-lever 2T is pivotallv mounted on the end ot' the bolt 31, and when the lork is in position to receive a load the opposite end ot the lever engages with a laterall,v-pro,iecting part 33, secured to the bars 29 and 30, and by means ot' the connectingcable maintains the forli in that position. rllo trip the forli to discharge the load, it is neecesar)v to disengage the lever 27 from the projection 33.

Pivotally mounted between the bars 29 and 30 upon a horizontal pivot is a sweep-lever 34C, aid secured thereto inside ot its pivotal connection 35 is a strap-bracket 3G, having an upward and outward inclined portion 37, adapted to contact with the hand-lever 27 and disengage it from the projecting part 33 when the lever 34C is raised at its outer end, as shown b v dotted lines in Fig. 4. The sweep-lever 34, in combination with the bars 29 and 30,

has the double function, securing and releasing the forli-controlling means and rotating the mast for the purpose of moving the fork Vfrom its receiving to its discharging position. When the fork is in position to receive the load, and while it is being elevated, the mast is locked from turning by means ot' the hook 3S, iiivotallwv mounted on the brace 9 and adapted to engage with the lever and hold it against the brace.

Mounted upon the cross-bar 3 of the base trame is a powcr-transmitting means 39, comprising vertical and horizontal sheaves suitabl)7 mounted and adapted to guide the rope 40, to which a draft-team is hitched in the usual wav. The rope passes over a sheave mounted at the upper end ot' the mast and is rove through the sheaves mounted at the upper end otl the jib and in the block 41, connected to the boom in the well-known manner.

By connectii'ig the boom to the mast above the upper ends of the lateral braces a wider range ol'l movement thereotI is obtained, and by connecting` the lower end ot the jlb to the boom beyond its pivot a better transmission ot' the power is obtained through the downward thrust ot' the jib as the forl is elevated. liv extending the side members otl the boom bevond their pivotal connection with the mast l and connecting them together b v means of the bridge piece 14 the boom is made much stronger to resist a torsional strain caused by an unequal distribution ot' the load upon the fork.

The angle ot' the teeth ot' the fork relative to the boom may be adjusted b v means of the connection between the cable and the handlever.
